Given numbers are 681,949,990,424

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 681,949,990,424 is 45212979240.

Find LCM of 681,949,990,424 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 227 x 949 x 165 x 212 = 45212979240

Therefore, the lowest common multiple of 681,949,990,424 is 45212979240.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

681 x 949 x 990 x 424 = 271277875440

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

681 : 1, 3, 227, 681

949 : 1, 13, 73, 949

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

424 : 1, 2, 4, 8, 53, 106, 212, 424

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,949,990,424, is 1.

Now, the common factors can be found like this.

681:3x 227

949:13x 73

990:2x 3x 3x 5x 11

424:2x 2x 2x 53

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3 = 6

Therefore, the value for common factors is 6.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 271277875440/(1x6)

LCM = 271277875440/6

LCM = 45212979240

Thus, we can understand that the LCM of 681,949,990,424 is 45212979240.
